On the Back Reaction Problem for Gravitational Perturbations
V. Mukhanov, L. R. W. Abramo, R. Brandenberger
We derive the effective energy-momentum tensor for cosmological perturbations and prove its gauge-invariance. The result is applied to study the influence of perturbations on the b…

Deflationary Models Driven by Matter Creation
J. A. S. Lima, L. R. W. Abramo
A nonsingular deflationary cosmology driven by adiabatic matter creation is proposed. In this scenario there is no preinflationary stage as happens in conventional inflationary mod…

Inflationary Models Driven by Adiabatic Matter Creation
L. R. W. Abramo, J. A. S. Lima
The flat inflationary dust universe with matter creation proposed by Prigogine and coworkers is generalized and its dynamical properties are reexamined. It is shown that the starti…
